Title: Astra overheating - AA man says water pump or head gasket
Post by: terry paget on 24 July 2019, 14:23:33
2010 Astra 1.6 petrol manual hatchback
Son Jonny rang me this morning, car flashing a temperature light. He pulled over , rang me, I said call the AA (he was about 40 miles away).  AA man found header tank cap not tight, so added water and tightened it, all still not well. No obvious hose leak, AA man delivered it home to me, suggesting water pump or head gasket. Car is now in my garage, cooling down.

Please advise.

There is a solid plastic pipe from the top of the stat housing to the throttle body at the rear of the engine.

Check it carefully, I have seen this go brittle and split (even crumble)

If the cap was not tight then the coolant will be lost ,especially in this weather  ::)
I advised you change the water-pump when you did the cam-belt  :P
putting cold water into a hot engine is a terrible idea  :-X

when it's cooled down, top up the coolant ,check the oil,
run the engine with the expansion cap off and check that there is not bubbles in the header tank
replace the cap
 run it up to temperature and check the stat opens and the fans kick in
the 2 pipes that go to the heater matrix in the engine bay (bulkhead) are a common leak area
hope they have not cooked the engine  :(

Also make sure the cap still has its innards!. I've seen the valves fall out if the cap gets dropped making the cap purely a decorative item rather than a pressure cap.
This was discovered on a friends car which only overheated on motorway runs but was OK short local journeys. Tell tale for checking the cap initially was that the hoses never pressurised up at all.

Thanks to all for advice. I was in despair, as 2 other cars were out of action, and son Dan had gone on honeymoon in my last Omega.

Having conveyed home Jonny & Elaine to Chippenham without their car, this evening I began to seek the fault. I topped up the header tank, and ran the engine to warm it up and watch for leaks. I plugged in my diagnoser.

No leaks appeared, and as the coolant temperature passed 96 degrees the fan engaged. Nothing untoward happened. No leaks, no steam.
After 15 minutes of the fan cutting in and out, I decided to take it for a test drive. Drove 10 miles, no problems.

The fault code P05967-16 appeared, and would not clear. I believe that is the thermostat code. Might it have failed shut?

I did not know my car had an electronic thermostat. The only thermostat I was aware of is the mechanical thermostat which resides at the left hand end of the block. Is that the one you refer to? I have changed one on another Astra. Do you reckon that could have caused today's problem?

like this clicky  (https://www.ebay.co.uk/itm/Fits-VAUXHALL-ASTRA-G-H-MERIVA-SIGNUM-VECTRA-C-ZAFIRA-1-6-1-8-COOLANT-THERMOSTAT/163629150405?fits=Cars+Type%3A1.6&hash=item26190eb0c5:g:vX4AAOSweuBcov-a)

is that what is fitted ? check the part numbers etc  :y

some have metal housings , some have plastic housings
beware , over-tighten the stat and the housing cracks
many sellers include a new housing
( so get the old one off, take it with you to compare  ;)
if you snap the housing taking the old one off ,you'll need a housing too

loose rad cap probably caused the main problem  ::) BUT you need to sort the stat anyway :y

The code was P0597-61, and looking on e-bay the Astra thermostats come in housings with electrical connections, so can be called electronic. Strange that the code should come up, and even stranger that I could not erase it. Much easier to change than the head gasket, though, or even the water pump.
Title: Re: Astra overheating - AA man says water pump or head gasket
Post by: dave the builder on 24 July 2019, 21:34:13
depends on how many housings you snap removing the old one and fitting the new one  ;D
water pump is a 15 minute job and i'm slow doing jobs  :P

 I'm going to say this, I will be the nasty man, Terry stop buying old scrappers, that you bodge up and send your family out in, because they keep going wrong on a regular basis, the amount you've wasted in the past 12months could have bought your daughter and son a decent low mileage car each,, Alternatively let them buy there own cars, and you could have a rest......

Just popped in my head  ::)
is this the Astra that had a crash and needs a bumper swap ?
in which case, check the radiator for leaks etc

any car, be it £500 or £50,000 will overheat if the rad cap is not tight  ::)

and if this is the one that needs a bumper , I bet Terry is glad it's a "old scrapper" he can put a bumper on from his stock  ;D :D
Terry is keeping busy and active
best of luck to him  :)
when I reach 80  :o I hope i can still fix "old scrappers"

they are past it *
Terry still gets the spanners out and has a go

*fixing cars

I'm not sure of Terry's exact age ,80 ish
don't think he can remember himself  ;D  :P

anyway, what's the alternative  :-\ finding a garage that will look after his family's cars without ripping them off

I hear a lot more about garages getting it wrong  , over-charging, miss diagnosing than garages that do a decent job for a fair price .

PLUS
Family is important , if you have the time and skill to help them then why not  :)

 I don't mind fixing, the cars that the family own, as they are all quite new and re++++, but Terry seems to go from one bad buy to another,  I hope when I'm his age I can still tinker about, and do routine service work, as well as Lord ooti style service.  It just seems every week one of Terrys eBay fleet breaks, or has a problem.

No. This is the first Astra I bought, and the best! 171,000 miles, given no trouble at all in 10,000 miles. I had it in for a service and MOT in May. I have been offered £2000 to write off the Astra needing a new bumper.

Accept the money put little more in and buy something a bit newer with less miles and some decent history,,,   But then £2k would buy 4 Astra's and you could make 1 good one out of all 4.   :P

Take the cash, buy back the salvage and fix it. You'll still be about £1,500 up 8)

It's just a wedge to stop the plug coming off
push the blue tabs inwards and pull it out ,then another tab retains the plug

Thanks. That's more or less what I concluded; I pushed it in and and through to the other end. It still seems superfluous, and a hindrance to later repairs.
New thermostat now installed, in a short road test all seemed fine. In the morning I shall give it a longer test, and, if all well, return car to my son. Looks like the AA were wrong saying water pump or head gasket.
Thanks to all for help.

he did. But Terry's talent is to buy crap examples of ordinary cars. We should consider it as a community service, as it removes them from the market so we don't end up with them.

I do observe a level of petty and inappropriate comments and sniping in this thread from a few, its uncalled for and not needed.

There are over 7 billion variants of human on this plant and growing, no two the same.

I personally applaud Terry for running a good number of cheap cars, cheaply.

Well Said  :y

I think some people don't realize Terry Looks after many cars  ::)
and all cars ,even new ones have an issue from time to time.
this miss-diagnosed (by AA) issue probably cost £50 to resolve including coolant  :-\

I wish I had a pound for every car that's over-heated this week , or a pound for every car  that the AA (or other breakdown provider) miss-diagnosed  ;D

Hopefully for Terry it's  "OK, that's fixed , on to the next one " Andrew Camarata style  ;D

Completely agree. If any of us are ever pushing 80, and still working on all kinds of cars we can criticise others who do the same.  :)

Well said that man, but it shouldn't need to be said  :'(


Granted, terry paget has had a fair few issues with some cars bought recently, but that is always a risk buying older cars.  But for the most part, it seems they have been cheap fixes, so all worthwhile :)

We all try to help our family when we can, and if terry paget's way of doing that is to provide working vehicles to his childern, surely that is to be praised, not berated  ???


And on top of that, I find the trials and tribulations of his cars interesting, and when I see him getting the help to resolve the issues, well, that makes OOF worthwhile to me.


Although I hope, and believe that no malice was intended in the posts in question.

I think it probably comes from a place of good intent - in that none of us want to hear that Terry keeled over while trying to fix an Astra/Omega/Corsa/etc for his kids.. but I also know what my Dad is like, who I literally cannot stop from turning up at our house to do DIY (he turned 71 this year).

If I have half as much energy as him at that age, I'll be a lucky man .. assuming I haven't croaked of a heart attack.
